When talking a local systems guru, Dave Liddell, he suggested I monitor my EC2 resources a little more closely. Using AWS EC2 is still just shared hosting.
This plugin allows you to monitor:
- steal time: CPUs while the hypervisor was servicing another virtual processor
- ping time
- EBS performance
Suggested thresholds:
Not sure yet, but I will update after I have more data. Here's where I'm starting.
- ping times above 75ms
- steal consistently above 20%
Reading http://www.igvita.com/2009/06/23/measuring-optimizing-io-performance they suggest:
- await and svctime above 50ms
- average queue size above 9
Actions to take:
If steal time is consistently high, that means your instance is on a physical server that is likely over allocated. Create a new instance to hopefully move it to another phyical node.
